Pearl Grossbeck - Pittsburgh

Pearl Grossbeck - Pittsburgh

I am searching for the grave of Pearl Grossbeck. She was born Iva Pearl Wetzel on July 13, 1895 or 1898 and died July 15, 1943. At the time of her death, her mother's name was Anna Schmidt (although I believe her maiden name was Derr) and she was living in Pittsburgh, PA. Pearl's death certificate says she was buried in the Zelienople Cemetery in Pittsburgh. Zelienople, PA is NOT in Pittsburgh, but it is somewhat near it. I have already contacted the Zelienople Historical Society and Pearl is NOT buried in the cemetery there, so now I have reached a dead end (no pun intended). If anyone has come across her grave or Anna Schmidt's in Pittsburgh, I would deeply appreciate it if you can tell me the location. Thank you!
